Procedures of the surgery
Firstly,
Percutaneous transluminal coronary angioplasty (PTCA) is a minimally invasive procedure to open up obstructed coronary arteries, allowing blood to circulate unblocked to the heart muscle.The procedure begins with the doctor injecting some local anesthesia into the groin area and putting a needle into the femoral artery, the blood vessel that goes down the leg. A guide wire is placed via the needle and the needle is removed. An introducer is then placed over the guide wire, after which the wire is removed. A different size of guide wire will be put in its place.
Secondly,
A long narrow tube called a diagnostic atheter is advanced through the introducer over the guide wire, into the blood vessel. This catheter is then guided to the aorta and the guide wire is removed. Once the catheter is placed in the opening or ostium of one the coronary arteries, the doctor injects dye and takes an x-ray.
Thirdly,
If a treatable blockage is noticed, the first catheter is exchanged for a guiding catheter. Once the guiding catheter is in place, a guide wire is advanced across the blockage, then a balloon catheter is advanced to the blockage site. And then balloon will be inflated for a few seconds to compress the blockage against the artery wall. Therefore, the balloon is deflated.
Last,
The doctor may repeat this action for a few times, each time inflating the balloon a little more to widen the passage for the blood to flow through. This treatment may be repeated at each blocked site in the coronary arteries. A device called a stent may be placed within the coronary artery to keep the vessel open. Once the compression has been performed, contrast media will be injected and an x-ray will be used to examine any changes in the arteries. After this, the catheter will be removed and the procedure is totally finished.
